For Z1-Z2 exercise there is a coupling of speed or power to HR. For a constant power/speed the HR should settle down to a constant value after a few …
The chart below shows the equivalence between the zones in different models. In the three zone (Lactate) model LT1 extends to 80% of HRmax and LT2 to 87 …
Rather than just randomly exercising or beasting it every time we go out we can use the zones to develop a targeted training programme. Training-intensity distribution (TID) defines how much …
How do you actually measure TID? The basic idea is to divide and quantify training time or distance into different intensity zones, over time frames from single sessions, to a …
A lot of the early data concerning Training Intensity Distributions is based on diaries of elite athletes rather than scientific studies. There are issues with comparing volumes in each zone …
A POL or PYR model works better than THR for both elite and club level endurance athletes. Seiler, who popularized the POL model recently suggested the three level zones could …
